ICU Nurse: Intensive Care Unit Nursing Career Guide
Intensive Care Unit (ICU) Nurses are specialized registered nurses who provide life-saving care to critically ill patients in hospital ICUs. Working with the sickest patients in the hospital, ICU nurses must possess advanced clinical skills, quick thinking abilities, and the emotional resilience to handle high-stress situations daily.
What ICU Nurses Do
ICU nurses care for patients with life-threatening conditions requiring continuous monitoring and complex interventions. They manage ventilators, monitor hemodynamics through arterial lines and Swan-Ganz catheters, titrate vasoactive medications, and respond to rapidly changing patient conditions. A typical ICU nurse cares for 1-2 patients per shift, allowing for intensive, focused care.
Common ICU Patient Populations:
- Post-surgical patients requiring close monitoring
- Septic shock and multi-organ failure
- Cardiac emergencies (MI, heart failure)
- Respiratory failure requiring mechanical ventilation
- Trauma victims
- Neurological emergencies (stroke, brain injury)
Salary & Compensation
Average Salary: $85,000 - $115,000 annually
Entry-Level: $75,000 - $85,000
Experienced (5+ years): $95,000 - $125,000
Shift Differentials: Additional $3-8/hour for nights, weekends
ICU nurses typically earn 15-25% more than general medical-surgical nurses due to the specialty's demanding nature and required expertise. Many ICU positions offer sign-on bonuses ($5,000-$15,000) and premium pay for call shifts.

Clinical Skills:
- Ventilator management (SIMV, APRV, PRVC modes)
- Hemodynamic monitoring (arterial lines, CVP, PA catheters)

- Continuous renal replacement therapy (CRRT)

Career Path
New Grad → ICU Nurse (if ICU residency program)
Med-Surg Nurse → ICU Nurse (most common path - 6-12 months experience first)
ICU Nurse → Charge Nurse (leadership role)
ICU Nurse → Clinical Nurse Specialist (advanced practice)
ICU Nurse → CRNA (nurse anesthetist - requires 1-2 years ICU minimum)
Many nurses view ICU as a stepping stone to advanced practice roles like CRNA, which requires critical care experience.
